Question | Answer |
When air is heated the particles move | further apart |
State a material which lets heat pass through it easily | conductor |
State a material which does not let heat pass through it easily | insulator |
Explain conduction in terms of vibrating particles | conduction involves heat energy being passed on by the vibration of particles. When the particles get hot they start to vibrate more and bump into the particles next to them. |
is air a good conductor of heat | no air is not a good conductor of heat because it's particles are too far apart and cannot pass on the vibration. |
What are heat rays also known as | Infra-red rays |
Heat transfer through gases and liquids | convection |
Heat transfer in solids | conduction |
What is a good conductor of heat | metal |
what is a good insulator of heat | wood |
Heat transfer through space | Radiation |
what is temprature measured with | thermometer |
the hotter a substance is | the greater heat energy it contains |
which colour absorbs heat better | black |
is cooper a better conductor than iron | yes it is a better conductor than iron |
the movement of less dense warm fluid upwards which is then replaced by cooler, denser fluid from below | convection current |
The ratio of the mass of an object to it's volume | density |
the scientific name for a heat picture | Thermogram |
a form of energy measured in joules | heat |

Give examples of conductors in the home | pots and pans |
